Although mammals and birds are widely regarded as the smartest creatures on earth, it has lately become clear that a very distant branch of the tree of life has also sprouted higher intelligence: the cephalopods, consisting of the squid, the cuttlefish, and above all the octopus. In captivity, octopuses have been known to identify individual human keepers, raid neighboring tanks for food, turn off lightbulbs by spouting jets of water, plug drains, and make daring escapes.

As a botanist and professor of plant ecology, Robin Wall Kimmerer has spent a career learning how to ask questions of nature using the tools of science. As a Potawatomi woman, she learned from elders, family, and history that the Potawatomi, as well as a majority of other cultures indigenous to this land, consider plants and animals to be our oldest teachers.

Suzanne Simard is a pioneer on the frontier of plant communication and intelligence; her TED talks have been viewed by more than 10 million people worldwide.

How do trees live? Do they feel pain or have awareness of their surroundings? Research is now suggesting trees are capable of much more than we have ever known. In The Hidden Life of Trees, forester Peter Wohlleben puts groundbreaking scientific discoveries into a language everyone can relate to.

Of all the things humans rely on plants for - sustenance, beauty, medicine, fragrance, flavor, fiber - surely the most curious is our use of them to change consciousness: to stimulate or calm, fiddle with or completely alter, the qualities of our mental experience. Take coffee and tea: People around the world rely on caffeine to sharpen their minds. But we do not usually think of caffeine as a drug, or our daily use as an addiction, because it is legal and socially acceptable.

This entertaining and mind-expanding journey will captivate listeners who are curious about the hidden worlds and networks that make up our planet.

Terence McKenna hypothesizes that as the North African jungles receded, giving way to savannas and grasslands near the end of the most recent ice age, a branch of our arboreal primate ancestors left the forest canopy and began living in the open areas beyond. There they experimented with new varieties of foods as they adapted, physically and mentally, to the environment. Among the new foods found in this environment were psilocybin-containing mushrooms.

In his articles and in best-selling books such as The Botany of Desire, Michael Pollan has established himself as one of our most important and beloved writers on modern man's place in the natural world. A new literary classic, Second Nature has become a manifesto not just for gardeners but for environmentalists everywhere.

In The Heartbeat of Trees, renowned forester Peter Wohlleben draws on new scientific discoveries to show how humans are deeply connected to the natural world. In an era of climate change, many of us fear we’ve lost our connection to nature - but Peter Wohlleben is convinced that age-old ties linking humans to the forest remain alive and intact. We just have to know where to look. 

A natural history of the wilderness in our homes, from the microbes in our showers to the crickets in our basements Even when the floors are sparkling clean and the house seems silent, our domestic domain is wild beyond imagination. In Never Home Alone, biologist Rob Dunn introduces us to the nearly 200,000 species living with us in our own homes, from the Egyptian meal moths in our cupboards and camel crickets in our basements to the lactobacillus lounging on our kitchen counters. You are not alone.

Sy Montgomery's popular 2011 Orion magazine piece, "Deep Intellect", about her friendship with a sensitive, sweet-natured octopus named Athena and the grief she felt at her death, went viral, indicating the widespread fascination with these mysterious, almost alien-like creatures. Since then Sy has practiced true immersion journalism, from New England aquarium tanks to the reefs of French Polynesia and the Gulf of Mexico, pursuing these wild, solitary shape-shifters.

Matsutake is the most valuable mushroom in the world - and a weed that grows in human-disturbed forests across the northern hemisphere. Through its ability to nurture trees, matsutake helps forests to grow in daunting places. It is also an edible delicacy in Japan, where it sometimes commands astronomical prices. In all its contradictions, matsutake offers insights into areas far beyond just mushrooms and addresses a crucial question: what manages to live in the ruins we have made?

Bill Bryson once again proves himself to be an incomparable companion as he guides us through the human body - how it functions, its remarkable ability to heal itself, and (unfortunately) the ways it can fail. Full of extraordinary facts (your body made a million red blood cells since you started reading this) and irresistible Bryson-esque anecdotes, The Body will lead you to a deeper understanding of the miracle that is life in general and you in particular. As Bill Bryson writes, "We pass our existence within this wobble of flesh and yet take it almost entirely for granted."
